  • Publication number: 20250084815
    Abstract: A fuel injection valve support structure simple in structure is provided which is capable of preventing a fuel injection valve from rotating about an axis of a valve housing thereof without providing a special rotation-preventing piece on an elastic support member. In this support structure, a base plate (15) of an elastic support member (S) is provided with a notch (19) which receives a valve housing (1). A rotation-preventing protrusion (20) which engages with the notch (19) to prevent rotation of a fuel injection valve (I) about an axis (A) of the valve housing (1) is formed on a synthetic resin formation part (6) which covers the valve housing (1) while protruding a coupler (14) to one side.

  • Patent number: 12162352
    Abstract: A display controller converts a detection target region contained within a detection range of an obstruction sensor group and extending from a vehicle to the periphery thereof into a virtual marker image and causes a virtual image to be displayed by superimposing the image over a scene in front of the vehicle. When the relative position of an obstruction is within the detection target region, the display controller causes an arc-shaped ripple spreading in a direction based on the relative position of the obstruction to be displayed in a region, of the virtual marker image, located in a direction based on the relative position of the obstruction. The display controller converts the important information into a notification image and causes the notification image to be displayed in a display medium. The display controller changes the display format of at least one of the virtual marker image or the notification image.
